The bluez-utils package contains Bluetooth daemons and utilities.
A flaw was found in the Bluetooth HID daemon (hidd). A remote attacker would have been able to inject keyboard and mouse events via a Bluetooth connection without any authorization. (CVE-2006-6899)
Note that Red Hat Enterprise Linux does not come with the Bluetooth HID daemon enabled by default.
Users of bluez-utils are advised to upgrade to these updated packages, which contains a backported patch to correct this issue.
